PENCIL-SHARPENER.

Specification of LettersP atent.

Patented Oct. '7, 1919.

Application filed December 4, 1917. Serial No. 205,367.

Be it known that I, WILLIAM WELLS CAV- ERLEY, a subject of the King ofGreat Britain, and a resident of the city of Vancouver, in the Provinceof British Columbia, Can ada, have invented certain new and usefulImprovements in Pencil-Sharpeners, of which the following is aspecification.

My invention relates to improvements in pencil sharpeners, and theobject of my invention is to provide a device of this nature adapted tobe carried personally with and on the pencil so as to be handy andconven ient for the sharpening of the same and which device is simple,useful, and inexpensive.

I attain this object by the construction illustrated in the accompanyingdrawings in which- Figure 1 is a front view of my device mounted on apencil.

Fig. 2 is a side view of Fig. 1.

Fig. 3 is a vertical cross sectional view of the device, taken throughthe center line.

Fig. 4c is a side viewof the eraser element.

Fig. 5 is a view of the opposite side of the eraser element shown inFig. 4:-

Similars figures of reference indicate similar parts throughout theseveral views.

The device consists of a tubular member 1, formed of suitable material,closed at its upper end to form a revoluble cap for the end of a pencil23 and in the interior of which at its upper end is secured in anysuitable manner a cutting blade 2, the edge of which blade is disposedso that the end of the pencil when inserted and pressed into the member1 will be sharpened thereby when the member 1 is rotated. As it isintended that the devicebe carried personally with detachable connectionthereto and this is effected by securing an encircling band 3 on theoutside of the member 1, the band being divided and threaded through twopairs of slots 4 5 and 6-7 respectively cut through the wall of themember 1 on opposite sides of the same and being turned outwardly at itsends to form lugs 8 and 9 through which a pin 10 is passed and rivetedover on each end to draw the band tightly onto the member 11,- on whichpin is fulcrumed a lever 11 the upper end of which is adapted to bear onand press inwardly a flexible strip 12 formed on the member 1 by thecuttingv oftwo slots 13 and 14 in the wall thereof, such inward pressurebeing produced by the act of inserting the pencil and sharpener into thepocket so that the edge of the same passes between the periphery of themember 1 and the lower end of the lever 11, from which it will be seenthat the strip 12 will then bear on the pencil to prevent the detachmentof the sharpener therefrom, but that when the pencil is removed from thepocket the pressure on the strip will be relieved, allowing the member 1to be rotated to sharpen the pencil if desired.

15 and 16 indicate a pair of jaw members formed on the end of member 1adapted to form a finger grip for rotating the sharpener, between whichjaws is adapted tobe inserted an eras-er element 17 to the lower edge ofwhich is secured a .metal clip 18 provided on one side with projections19 and 20 adapted to co-act springably with sockets 2l'and 22 formed onthe inner face of jaw 15 so as to detachably secure the eraser elementin place between the jaws 15 and 16.

From the foregoing it will be seen therefore that I have devised asimple, efiective, and inexpensive pencil sharpener which, on account ofits being carried on the pencil in the form of a cap, as it were, is ofgreat convenience and usefulness.

What I claim as my invention is:

1. A pencil sharpener comprising, a revoluble cap adapted to inclose apencil end and provided with an interior cutting blade, an integralflexible strip formed in the wall of the cap and a lever mounted on saidcap capable of being operated to force the flexible strip of the capinwardly against the pencil. i 2. A pencil sharpener comprising, arevoluble cap adapted to inclose a pencil end provided with an interiorcutting blade and an integral flexible strip on one side, and a suitablyfulcrumed lever mounted on said cap adaptedito co-act with said stripand capable of being operated to force said strip against said pencil.

3. A pencil sharpener comprising, a revoluble cap adapted to inclose apencil end providedwith an interior cutting blade and a depressiblestrip onrone side, an encircling band secured to saidcap, and a leverfulcrumed on said band and adapted to control 7 the depression of saidstrip. r 4:; A pencil sharpener comprising,- arevo-' 2 -5 pairsof slots,a divided band threaded Dated at Vancouver lublegcap adapted to inclosea pencii'end progether, anda lever {dimmed on said pin,
